To all whom it may concern: I

Be it known that I, JAMEC. =Bm-zso residing at Tro in the county of Miami and State of bio, have invented a new 5 and Improved Seed-Cleaner and Grain- Separator, of which the following is a specification. r This invention primaril has for its object to provide a seed ceaner and grain 1 se arating machine of a sim le and economica construction, arid in w ich the several parts are cooperatively so combined and arranged for'elfecting a proper and desired cleaning and distribution of the cleaned seed,and the said-parts are especially desi ed for being easily put up and mamtained for their practical operation. My resent invention has for its to provide an improved and simpified means 3 for agitating and vibratin the several screen carrying frames or. s oes, and for adjustably mounting the hopper with its ad ustable feed board.

A ain, my present invention embodies a nove and improved mounting of the main or se arating screens and carrier thereforand. e final screening devices.

My invention further seeks to provide an improved means for directing the fan blasts 3:).for efiectin a positive and quick separation of the cha and trash from the rain and with other objects in view that w1ll hereinafter appear my said present invention consists in the peculiar construction and novel combination of parts .all of which will be hereinafter fully explained, be specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which: y

Figure 1, is a rspective view of the invention. 'Fi 2, is a vertical longitudinal section thereo Fig. 3, is a transverse section taken substantially on the line 3-3 on Fig. 2. Fig. 4, is a similar view on the line 46-H- on Fig. 2. Fi 5, is a plan view of the delivery end of t e central screen carrying shoe, arts being broken away, to show parts of t e bottom shoescreen. Fig. 6, is a similar view of the discharging end of a 50 the lower screen carrying shoe. Fig. 7, is

a detail cross section of one of the hopper adjusting devices hereinafter referred to of i! the practical arran ment m resent 8 3' P V invention includes a supporting frame comprising; the front and rear pairsof end legs terofthesee object I which are threaded toreceive" the holding the hopperin' a fixed 1-1-2--2, the central pair; of uprights or legs 3--3, braced by the base members 4-4 2nd one or more sets of horizontal braoe' '5; 6 designates'the ho per thatis mounted between the upper en of the legsoaf standards1-'-3 and in" the oonstructionkhown the said hopper is adjustabl mountedrelp tively to the'iipper or cha shoe 8, so that the throat-or ischar between the hop r and the receiving an of the said 7 may be readil refiated to suit the to cleaned 'andyse e For effecting the adjustabilityof "hopper, I prefer to use the best s'hown 1n Fi 1 and 2, byreference to which it, will 'seen'the hopper is heldf between the upper ends of the, 1 and 2, by crossrods 7-'-'- 7, theendsfof nuts 70-970 that engage, the" 1 and 2, it bein obvious that by" tightening the said nuts t hopper can befix'edlyflan firmly held in the esired position. The hopper at each end and at oppositesides has a pair of bracket irons a bearings 15, that merge with the verti slots 0, the said slots andbearin' v1 ash relationthgz an one oft o arings a can ;-sli onto the H ping, rods 7, it being clear that to effect tradesired adjustment of the hoppefr only necessary to first shift the said hopp erlboglily in the irection indica by the arrow :0, and then raise or lower it' to thefpo'sition desired andlthen shift the'said hoppei'lbjody bodily in the direction 'of the may,

9 desi atesthe slide gate in thebottom of the opper which rides between the guide cleats 90 'and near the lower end and of the hopfper and whose outer ends have levers 12 r engaging rack guides 13- -143 By reason of the construction shown and described a simple and ine single means is provided for limping on the under sideit has bearings 79 with I which join the link rods 91 that extend naive and 1 0 for shifting its'discharge end with respect to the upper chaff shoe.

The upper chafi shoe Sin my present invention is shown with a sin le coarse screen 80 mounted in the lower ei lge of the box frame 81, the inner or head end of, which is supported by the oscillating bars 828 2 IEUlGIUlllBCl at 82*on the sides of the extension or nozzle end 18 of the fan casing 18, the outer or nose end of which stops under the delivery end of the screen 80 which isloosely mounted and oscillates on the roller bearings '8383.

2O designates the intermediate combined chafl' and separating shoe the receiving end of which extends up to near the fan'chamher proper and directly under the delivery openin chamber, the bottom 18 of which takes the droppings through the upper chaff screen a and delivers them onto the intermediate screens, as is best shown in :Fig. 2, by refer ence to which it will be noticed the fan chamber includes a lower or supplemental extension 18 that extends under and nearly the full length of the intermediate shoe, the

18* ofthe nozzle end of the fan outer or nozzle end 18 stopping just in advance of the delivery ends .of the several screens forming a part of the said intermediate shoe, whereby to direct the blast directly under the said delivery end to blow out the' chafl and other light particles that pass through and from the intermediate shoe screen through the outlet 22 in the supplemental or collecting pocket 23 that cx tendstransversejly under the front end of .the intermediate shoe that inclines down wardly and rearwardly and whoseinner end is open whereby to direct the droppings into the said pocket 23 on the lower or final separating and cleaning shoe, presently fully describe I It will be noticed by again referring to Fig. 2, the vbot-tom ofthe intermediate shoe .is closedto a' point near the forward or nose endiof the blast'chamber 18 such arrange .ment providing :for a concentrated blast.

through. the pocket and'up through the screens in the delivery end of the intermediate shoe that insures the positive blowing oil of the chaff at the said deliveryend,

it being understood that the upper nozzle portion of the fan chamber-acts in a like nmanner for separatingcthe. chaff from the p grain that-pours over thenpper or coarse 1 i screen. By placing the receiving end of the 1 shop near the fan chamber proper, a

. $imple and effective; means is provided for, ,div1ding and directing the blast in theman- ,ner; statedand italso provides, as it were,

two distinct, airpassages, one above and the other below theshoeQO, and. of such form that .the force and direction of the blast tiisough either passage can .b readily regu- 6 lated by theiupper and'lower wind boards 24-25, that are adjusted by the set screws 24.25 in the usual manner.

In my present invention, the intermediate shoe has a series of screens each set of which comprises a plurality of independent screening surfaces and these are of zinc, having graded apertures, the two upper sets of screens in practice having the largest apertures for separating the big from the little seed,'while the second set of screens are of such mesh that they separate the cocklc from the little grains. For separating the oats from wheat, each set or series of the zinc screens is provided with the loosely held flexible, preferably, oil-cloth curtain 27, under which the long grainv seed work while the larger or round seed passes thereover, 1n the manner well known to those skilled in this art.

The shoe 20 at the upper end is hung on the lower end of the hanger bars (Land its lower or discharging end is held on roller bearings 23-23.v

60' 60 designate link rods one end of which is eccentrically connected to the s rocket wheels 61411, on the fan shaft, t eir outer ends being pivotally connected to the upper ends of oscillating levers (E 62 fulcrumed on a-stud rod (33 and whose lower ends are pivotally mounted in the brackets Seton the elevated end of the lower shoe 43, again referred to. The levers or hangers 62-66 are fulcrumcd on the l'lorizontal beams of the main frame, and both sets of the said levers are crank-shaped and their lower or crank ends (lQ HKW extend forwardly in the direction of the discharging end of the lower shoe 4.3 to which the said ends (E -436 are pivotally connected, as best shown in Fig. 1. The lower shoe 43 which is loosely held on the hanger leversto swing in the direction of its length has two wire screens 44'45 of different mesh whereby to maintain the proper separation otthe different grades of grain that pass down from the middle shoe and the grain that passes downthrough the said two screens 44-5 trapped by the strip flanges 44-45, so as to pass out through the openings 44"-l-5, onto a divided partition 46 that leads the seeds into the receivers 47-48, it being understood that the good seed pass off the end of the screens 4445.

. the complete construction, the operation and the advantages of my present invention will be apparent to those skilled in, the art to which this invention relates.

By reason of moui'iting the three shoes as shown and described a simple and effective means is provided for inniarting the re quired constant agitation to the said shoes and their screens. the crank fm-n'iatirm of the l'iangers serving to impart a litt-junip-action to the lowermost shoe and its screens which causes the seed thereon to he constantly jarred u 'nvardly from the lower semen and thereby et'l'ect a perfect separation of the good from the foul seed. The dust chatlt', and other light rnhhish is positively blown out of the grain before it gets down onto 1 the bottom shoe, and screens, the two sets of blast nozzles arranged as shown and described serving to blow off sina ll sticks. \veed seeds and other light trash and in such manner that the proper screening and separation of the seed is materially assisted.
